Digests are finding aids that serve as a means of locating cases by subject. West Publishing, as a major publisher of federal and regional reporters, developed a unique subject classification of law known as the Key Number System and applied the classification to cases by creating editorial enhancements known as “headnotes.” “Headnotes” are paragraphs created by editors at West Publishing that summarize the important points of law discussed in a case and are assigned a number (“key number”) in the classification scheme. Digests arrange the “headnotes” of cases by subject in order to allow research by subject.
West published digests include a Descriptive-Word Index, a high detailed, alphabetically arranged subject index. The Descriptive-Word Index is often the best place to begin research when using digests. The Descriptive-Word Index provides citations to specific topics and key numbers in the digest.
